SPECIFICATION forming part of Letters Patent No. 774,431, dated November8, 1904 Application filed February 25,1904: fierial No. 195,299. (Nomodel.)

To aZZ w/wm it may concern.-

Be it known that I, FRED M. IRELAND, a citizen of the United States, anda resident of Portland, in the county of Multnomah and State of Oregon,have invented a new and useful Excavating-Bucket, of which the followingis a specification.

M invention relates to excavating imple-- ments, and has for itsobjectto provide adevice which 1s serviceable for use both as an excavator anda conveying bucket. To this is converted into a bucket adapted to besuspended by a tackle from a derrick and to carry and discharge its loadlike the common bucket. These various contrivances are constructed asillustrated in the accompanying drawings, hereby referred to as a partof this specification, and are hereinafter fully described and claimed.

In the drawings, Figure 1 is a side elevation of my excavating-bucket.Fig. 2 is a rear end elevation. Fig. 3 is a perspective of my inventionlooking at the same from the front end, and Fig. 4 illustrates themanner of using my invention.

Referring now to the letters as designating the parts described, thebody (Z is made of sheet-iron of suitable strength, the bottom (4thereof being made flat, so as to adapt the same to be dragged over theground in suitable position for doing the excavating-work.

Hingedly secured to the front end of the body a is a plate a or plow,provided with a rigid arm 0, connected by a link (Z with a lever f,pivoted to a bracket secured to one side of the body. The lower end ofthe lever f is bent, as seen in Fig. 1, and the end of thelink (Zconnecting therewith is forked.

The function of the plow Z) is to plow or dig up the ground in advanceofthe travel of the excavating-bucket and also to feed the dug up dirtinto the body of the bucket.

The plate 7) may be thrown in active and inactive position bymanipulating the arm f. When my excavating-bucket is started on itswork, the lever f is set in the position in which it is shown in Fig. 1.The operator may also when necessary bear down upon the extremity of thelever f, so as to hold the plow more effectively to its work. i

As soon as the bucket-body has become sufficiently filled withexcavated'material the operator reverses the lever f and by so doinglifts cutting edge of the plow?) off the ground.

The excavating-bucket consequently does no further excavating for thattrip, but merely proceeds to its place of discharge. There is alsoattached'to the front end of the body of the bucket a hauling yoke orbail it.

To the rear part of the body are pivotally secured on each side runnersj. The front ends of said runners j are pivoted in place, while the rearends of the same are connected, by means of links it, with the lowerextremities of a yoke-like lever Z, said lever being pivoted to lugs m,riveted on each side of the body.

The runners j are provided for facilitating the starting of theexcavating-work with my implementthat is to say, supposing the surfaceof the ground which is to be excavated to be level, to make the firstdeep cuts into the surface the body of my excavating-bucket should betilted, so as to throw the greater part of the weight of the body ontothe front (plowing) end. After the deep cuts have been made the runnersare returned to their normal position and only again thrown into theiractive position when required for making further deep cuttings. Saidrunners j are thrown into and held in their uplifting position bymanipulating the lever Z, as shown in Figs. 1 and 3. The lower ends ofthe two parts or branches of the lever Z are pivoted at Z. Beyond saidpoints the links Z: are pivoted to the said ends of the lever. The lowerends of the links it are connected with the ends of the runners j. Theupper ends 1c of said links are bent at right angles, and said bent endsare inserted in holes therefor made in the two ends of the lever Z. Thebent ends are threaded and secured in place by bolts k At the extremeends of each branch of the lever Z are provided rigid hooks Z Thus whenthe lever Z is thrown into the position indicated in broken outline inFig. 1, placing the runners in the position shown by their dottedoutline, the hooks Z will engage with the links 7: and the weight of thethrownback upper end of the lever Z will then cause said parts to remainin the described engagement and securely hold the runners j in theiractive position.

Hinged to the back end of the bucket-body is a door 72, provided withhandles a. The door is locked by means of a spring-latch 0, the door abeing made with a projecting portion n having an aperture 19, adapted toreceive the latch 0.

The back end of my bucket is further provided with a ring q, to which tosecure the ends of the haul-back cable.

The operation of my device is as follows: My excavating bucket is hauledover the ground by a donkey-engine or other suitable means, thehauling-line being guided through a snatch-block r, secured in suitableposition.

Upon the excavating-bucket having arrived at the end of its haul thehauling-cable is released from the snatch-block 1' and the bucket,filled with excavating material, lifted by means of a derrick-tackle.The derrick is next swung around, so as to bring the excavating-bucketin position for discharging into a wagon or other suitable conveyance,whereupon the latch 0 is lifted to drop the door n and allow thecontents of the bucket to discharge. The bucket is then hauled back tothe starting-point, the hauling-line is reinserted in the snatch-blockr, and the excavating operation is resumed.

The chain 2' is provided to hold the bucketbody in straightperpendicular position while suspended from the derrick-tackle. For thispurpose one end of the chain Z is permanently secured to the body, andthe other end has a ring 71 which is placed on the loop 5 of the bailit.

Having fully described my invention, what I claim, and desire to secureby Letters Patcut, is

1. In an excavating-bucket, the combination of a semicylindrical body,having a flat bottom; a plow-plate hinged to the front edge of thebottom; means for controlling and adjusting the position of said plow;runners pivoted to the two sides of the rear end of the body; means fordropping the runners, so as to tilt the body on its front end; a hingeddoor closing the rear open end of the body, and a latch for the door.

2. In an excavating-bucket, the combination of a semicylindrical body,having a flat bottom; a plow-plate hinged to the front edge of thebottom; a lever f pivoted to one side of the body, jointed connectionsof said plowplate therewith, whereby the plow-plate may be suitablypositioned and controlled; runners 7' pivoted to the two sides of therear end of the body; a yoke-like lever Zpivoted to the body; meansoperatively connecting said lever Z with said runners, whereby thelatter may be dropped, so as to tilt the body on its front edge; ahinged door closing the rear open end of the body; a latch therefor, andmeans for perpendicularly suspending the body from a tackle.

3. An excavating-bucket comprising a semicylindrical body, havingaflatbottom; a plowplate 6, hinged to the front end of the bottom; a lever fpivoted to one side of the body; jointed connections of said plow-platewith the lever f, whereby the former may be suitably positioned andcontrolled; runners j pivoted to the two sides of the rear end of thebody; a yoke-like lever Z, pivoted to the body; means operativelyconnecting said lever Z with said runners, whereby the latter may bedropped, so as to tilt the body on its front end; a hinged door closingthe rear open end of the body; a latch therefor; and a bail it and astay-chain t for perpendicularly suspending the body from a tackle.

4:. An excavating-bucket comprising a semicylindrical body, having afiat bottom; a plowplate 6 hinged to the front edge of the bottom; alever f pivoted to one side of the body, a rigid arm 0 on theplow-plate; a link (i connecting said arm with the lever f, so that theplow-plate may be suitably positioned and controlled by the lever f;runners j pivoted to the two sides of the rear end of the body; ayoke-like lever Z pivoted to the body; links in connecting the ends ofthe lever Z with the movable ends of the runners, and hooks or stops Zon said lever ends, so that said runners may be dropped, to tilt thebody on its front end by operating the lever Z; a hinged door 22,closing the rear open end of the body; a latch therefor and a bail h,and stay-chain t' for perpendicularly suspending the body from a tackle,

In testimony whereof I have hereunto affixed my signature in thepresence of two witnesses.

FRED M. IRELAND.
